BALL-BEARIN'IG. FOR HYDRAULIC GIANTS.

Specification of Letters Patent.

Patented July 24, 1906.

To all whom it may concern:

Be it known that I Momus L. GORDON, a tates, residing at Seiad Valle inthe county of Siskiyou and State of Ca ornia, have invented new anduseful I li iants, of which the following is a specification.

My invention relates to hydraulic giants, end particularly toantifrictional j oints there- The invention consists of the parts andthe construction and combination of parts, as hereinafter more fullydescribed and claimed, having reference to the accompanying drawin s,in'whichigure 1 is a sectional view of my joint for hydraulic ants. Fig.2 is a section taken on line X of Fig. 1.

A represents a stationary pipe-section connectin .with a suitable sourceof water-supply. his sup ly-pipe is often twelve or more inches in'ameter and the water flowl'l gdthrough it under several hundred feetThe section A is provided with an annular flange 2 which is perforatedto receive the bolts 3, by which the annulus 4 is removably iecured tothe top of the flange, said annulus em whic intersect the bolt-holes inthe annulus, with the nuts 6 seating in the slots and fitting the bolts3, as shown.

The portion of the annulus which seats on the flange 2 is madesufliciently thick and heavy to afford a good anchora e for the bolts 3against the tremendous t st that the water exerts in the nozzle 7. Theannu lus extends out beyond and all around flange 2, and its under sideis provided with an an-- nular oove, which forms the upper race for theba ls 8. The nozzle 7 is curved, like most nozzles of its class, and hasan annular flange 9 to seat and turn with a sliding movement on theannulus 4. The flange 9 extends beyond'the flange 2 and ring 4 andcarries a Wearing-ring 10, removabl held to the under side of flange 9by the b0 ts 11 and suitably spaced from the flange by the ring 12. Thering '10 projects in under the corresponding projecting bearing portionof ring 4 and has a groove on its upper surface, forming the lower racefor the balls 8. The inside diameters of the two rings 10 12 areslightly greater than the diameters of the respective adjacentmgrovements in Ball-Bearings for Hydrau' 0 provided with inside radialslots 5,.

arts of flange 2 and ring 4, so that a limited ateral ad'ustment of ring10 relative to ring 4 is possib e to allow the balls to seat and centerproperly in the grooves.

Interposed between flange 9 and rings 4 and 12 and carried by andmovable with the nozzle is an annular waterproof packing or plate 13, ofsuitable material which rests on rin 4 and bridges the space betweenrings 4 an 12. This ackin or cover member 13 has its inner e'ge sustantially flush with, but not projecting over, the inside wall of thering 4.and has an annular portion14 of its up er surface entirelyuncovered by flange 9 an completely exposed to the body of water in thenozzle.

Since the water in the nozzle is under very hea pressure, due to thehead-and to the restricted character of the discharge-orifice of thenozzle, a strong pressure is brought on this exposed surface 14 to causeit to hu close to the ring 4. Consequently any leal that takes placethrou h the joint occurs between .the packing an 'flange 9 and notbetween the packing and ring 14, so that practically no water gets intothe bearings, and they are protected from grit and other likedestructive agencies and tendencies.

In order to expose the edge of the packing sufficiently to t e internalwater-pressure, the nozzle adjacent to the flange 9 1s shown as cutaway, as at 15.

. In case any of the bearing parts become worn, as they inevitably do,it is an easy matter to replace any one of them without having todiscard an expensive nozzle or a specially cast and ground pipe-section.If the lower bearing-ring 10 becomes worn, it can.

quickly be replaced. So can the ring 4, which latter constitutes anessentially novel feature of the invention. These rings arecomparatively cheap, and by having them easily replaceable the miner canalways keep his giant in good workin shape with little cause oropportunity for eakage.

Having t us described my invention, what Iclaim, and desire to secure byLetters Patent, is-

An improved hydraulic giant havin in combination a pipe-section providedwit an annular flange, a nozzle-section having an annular flange aboutits base, a packing-annulus interposed between said flanges, saidannulus having radial recesses, bolts extending between the flange ofthe pipe-section and IIO the annulus, nuts fitted to the bolts andlocated in the radial recesses of the annulus, a wearing-ring secured tothe nozzle-section and underreaching the annulus, a packing between theannulus and flange of the nozzlesection and antifriction-rollers betweensaid annulus and the Wearing-ring.

In testi mony whereof I have hereunto set my hand 1n presence oftwosubseribing witnesses.
